The Sanger sequencing instrument is a piece of laboratory equipment used for DNA sequencing. It is named after Frederick Sanger, the British scientist who invented the Sanger Sequencing Method, also known as the chain termination method. The Sanger sequencing instrument automates the sequencing process by performing the various steps required for DNA sequencing, such as DNA amplification, DNA denaturation, primer annealing, and extension. It allows researchers to determine the exact order of nucleotides in a DNA molecule, which is crucial for many biological studies, including genetic research, disease diagnosis, and forensic investigations. The instrument is equipped with a laser and fluorescent detectors to detect the different colored fluorophores attached to the terminating nucleotides during the sequencing reaction. These fluorophores emit light at different wavelengths when excited by the laser, and the instrument reads the emitted light to determine the identity of the nucleotide at each position in the DNA sequence. The Genetic Analyzer Forensic Dna Instrument is typically coupled with automated capillary electrophoresis, which separates the DNA fragments based on their size and charge. After sequencing, the instrument analyzes the electropherogram, a graphical representation of the DNA sequence, to determine the order of nucleotides.

The usage of Sanger sequencing instruments has revolutionized DNA sequencing and enabled numerous advances in molecular biology. It has been widely used for sequencing small to medium-sized DNA fragments, such as individual genes or sections of genome assemblies. However, it is not suitable for large-scale sequencing projects due to its low throughput and high cost compared to next-generation sequencing technologies. In summary, the usage of Sanger sequencing instruments allows researchers to accurately determine the DNA sequence of various biological samples. It has played a vital role in advancing our understanding of genetics and has been instrumental in numerous scientific discoveries and applications.
